Blade of Truth is a Weapon Augment Mod that increases melee damage and Truth specifically for the Jaw Sword. It increases melee damage by 25% and Truth by 0.25 per rank, at a maximum of 100% and 1 at rank 3, respectively.
While the Jaw Sword is the active weapon, Truth causes affinity gained by Jaw Sword to fill a special meter. Once the required amount of affinity is acquired, the weapon discharges a radial attack dealing 1,000 Gas damage to enemies around the player, restores 25% of maximum Health, and boosts all 3 parkour 2.0 stats (wall latch time, aim glide time, bullet jump speed/range) by 25%.
- This mod is acquired by attaining the rank of Crusader with the Arbiters of Hexis, and spending 25,000 to purchase.
